The main object of the present invention is to provide a simple andetlicient mechanism whereby pulverulent material such, for instance, asscrap tobacco and the like may be automatically weighed, placed in a bagor like closure, a coupon, card or the like placed within the bag, thebag thereafter sealed, and a revenue stamp or the like applied to saidclosed bag which is automatically discharged from the machine.

It is conceivable, of course, that the package may-or may not have acoupon or the like placed therein, and it is likewise conceivable thatif the material being packaged does not require the presence of arevenue stamp said stamp may be omitted, or a label or like band placedthereon in lieu of the stamp.

A further object of the invention is to provide a simple and etiicientholder for the bags, upon which they may be readily placed by anattendant, the construction being such that the operation of positioningthe bags may be easily and readily effected,

and this without the necessity of employing a skilled workman.

Another object of the invention is to provide a simple and efficientmechanism for feeding the coupons to the package.

A further object of the invention is to provide mechanism for tucking inthe ears of the closed bag and also means for closing find sealing thenormally open end of the i still further object of the invention is toprovide an efficient stamp-applying mechanism in conjunction with whichWorks a special means for holding the last inturned flap of the bag inits closed position and also means for holding the stamp which-has justbeen applied to the up-turned end of the bag in place thereon until ithas become securely attached thereto.

With these and other objects in view a detailed description of theinvention will be given.

The machine herein set forth is especially designed and employed for thepurpose of packaging scrap tobacco, though it is equally applicable forthe packaging of other materials.

Referring to the drawings, 1 denotes the base or table beneath which ismounted a shaft 2 (see Fig. 5) upon which is loosely mounted a drivingwheel 3, the shaftlikewise having a clutch 4 (Fig. 4) splined thereonand adapted to cooperate with a clutch member carried by the wheel orpulley 3. A suitable treadle or like mechanism will be employed to throwthe clutch into and out of operative relation with the driving wheel. A.pinion 5 is secured to the shaft 2 and meshes with an idler 6, which inturn meshes with. a large gear 7 secured to a cam-carrying shaft 8. Saidshaft has secured to it a series of cams, .a cam 9, which serves toraise and lower the shaft upon which the-carrier or support for thebag-forms or holders is mounted; cams 10 and 11, formed on the oppositefaces of a single casting 12, cam 10 serving to actuate the packer, andcam 11 to actuate the coupon feeding mechanism, and the initial folder;cams 13, 14;, formed on the opposite faces of a single cam disk ormember15, cam 13 serving to actuate the package elevator or push member whichremoves the package from the form turret into operative relation withthe stampfand the cam 14 serving to actuate the push-bar which removesthe completed and stamped package onto the delivery table; and a cam 16which actuates the stamp-positioning mechanism.

Secured to the shaft 2 is a bevel gear 17 (Figs. 2 and 5) which mesheswith a pinion 18 mounted upon the lower end of a vertically-disposedshaft 19, said shaft finding its support at its upper end in a bracket20 which in turn is supported by one of a series of U-shaped arms 21extending outwardly from a vertically-disposed post or column 22 mountedupon the bed or table 1. Said column and arms 21 form the support forthe weighing mechanism, shown in section in Fig. 2, which mechanism perse is reserved for a separate application but is herein shown in orderthat the invention may be fully understood and claimed. Secured to theupper end of the shaft 19 is a bevel gear 23, which in turn meshes witha bevel pinion or gear 24 mounted upon the outer end of a shaft 25 whichserves to rotate the weighing mechanism and to successively bring thescalepans 26 thereof into proper position with relation to a funnel 27through which the materialis delivered into the bags or like containers.

A stirrer 28 (Fig. 2) works in conjunction with the weighing mechanismand serves to break up the material in order that it may be properly fedto the pans. Said stirrer is carried at the upper end of avertically-disposed shaft 29 which extends upwardly through the column22, the shaft at its lower end carrying a bevel pinion 30 which mesheswith a similar pinion 31 (Fig. which latter is carried upon a stubaxle32, which axle likewise has secured to it a ratchet-wheel 33, with whichcoacts a pawl 34, pivotally mounted at the upper end of a link 35. Saidlink in turn is like wise pivotally connected to a rocker-arm 36,

swiveled upon the stub-axle 32, and at its lower end to an arm 37 whichcarries a roller 01' bowl 38, working in conjunction with the cam 9.Through this mechanism an intermittent motion is imparted to the'st-irrer 28. The arm 37 is fulcrumed upon a fixed shaft or rod 39 whichlikewise forms the support for the various arms or levers which areactuated by the cams hereinbefore referred to. Said arm 37 at its outeror free end has pivotally connected to it a link 40 (Figs. 1 and 2) towhich in turn is pivotally connected a block 41 provided I in its upperend with a recess into which extends the reduced-end of a stem 42secured to or formed upon the lower end of a vertically-disposed shaft43, which shaft supports the carrier upon which the bagforms or holdersare mounted. The shaft at its lower end finds its support in a bearingformed at the lower endof a bracket 44, a second support being providedin a collar or hearing 45 secured to the upper face of the bed ortable 1. Intermediate said supports the shaft has splined to it a gear46, the connect-ionbeing such that the shaft may move through the hub ofthe gear as it is raised and lowered through the action of the arm 37and the cam 9. Motion is imparted to the gear through an idler 47 whichin turn meshes with a gear 48 secured to the upper face of the actuatingand locking disk 49 of a Geneva movement secured to a shaft 50, whichdisk coiipei ates with a stud or roller 51 (Fig. 5) carried upon theouter end of an-arm 52. Said arm is secured to a shaft 53 which alsocarries a bevel gear 54, meshing with a similar gear 55 secured upon ashaft 56 (Fig. 1), to the opposite end of which is secured a bevel gear57 ,Which meshes with a similar gear 58 carried by the shaft 8. It willthus be seen that through this gearing astep-bystep rotation will beimparted to the shaft 43 and also to the'shaft 50, which latter carriesthe form-turret hereinafter referred to. It will likewise be noted thatby reason of the proportioning of the gears 46, 47 and 48, as shown inFlg. 1, for every quarter revolution of the shaft 43 the form-turretwill be given one-sixth of a revolution. Shaft 43, adjacent to its upperend, is reduced and provided with a washer 59, upon which rests a block60, having a cam-race or way 61 formed therein, the cam being bestillustrated in Fig. 7, upon an inspection of which figure it will benoted that the cam is provided with a straight run at the lower portionthereof and likewise with a straight run at a higher level, whichstraight sections are connected by an intermediate inclined section uponeach side of the cam. This cam is held against rotation by an arm 62which extends outwardly therefrom, the arm being provided at its outerend with a rectangular opening into which projects a post 63 secured atits lower end to a projection 64 extending outwardly from the collar orbearing 45. Any means may be employed, however, for securing the post inposition.

To the outer end of the arm 62 is secured a U-shaped striker-plate 65,the downwardly-projecting fingers of which, as the shaft 43 is lowered,coact with rollers 66 mounted upon the upper short ends of the levers orarms 67, 68, which arms are fulcrumed upon pins or screws extending out-Wardly from the projection 64. A SIJIlllfI' 69, secured'to the upperends of the arms 67, 68, tends normally to drawthe inner ends of saidarms together and to spread the lower ends, each of which is providedwith an inwardly-projecting flat finger 70, which fingers, when drawninwardly through the action of the striker-plate 65, tend to tuck orturn in the outwardly-pmjecting wings or flaps 71 of the lower closed'endof the bag 7 2 from the position shown .funnel 27 through one of thebag-holders.

if perchance the bag should not be placed upon such holder.

' Secured to the shaft 43 above the cam 61 1s a spider frame providedwith four outwardly and downwardly extending arms 76. said arms beingalike in form and each provided at its lower end with ahorizontallydisposed bearing for the short shaft 77, the shaft at itsinner end having secured thereto an arm 78, the end of which is providedwith a roller 79 that enters the cam groove 61. To the opposite end ofthe shaft 77 is secured a loop-shaped member or strap 80. which carriesa hag-holder formed of spring sheet metal. and comprising a flattenedtubular section 81 having at its lower end two outer face of the bag,

at the upper end of the .slit. By reason of this construction the arms 82 and 83 may: be forced together by hand preparatory to slipping the bagthercover. ln the present instance I have shmvn a waterproof bag orliner 86, which'is placed within the bag 72, and these bags may bemounted upon the lower end of the bag-holder separately or preferably ina nested condition; that is to say the waterproof-bag is placed withinthe other bag and the two then slipped on simultaueously.

On account of the form given ,to the cam 61, it will be seen that thebag-holders will lie in a substantially horizontal position or planeduring one half the revolution of the shaft 43 and will maintain avertical position during the remainder of the revolution. As will beseen upon reference to Fi 3, the holders assume a horizontal posltionwhen they are moved adjacent to the outer edge of the table, in whichposition the operator will readily place the bags thereon.

Secured to the upper end of the shaft 43 is a horizontal arm 87, whichextends to a point adjacent to the column 22,- which column is providedwith guides or ways 88 (Fig. 3) for the reception of a guide roller 89secured upon the adjacent end of the arm 87. Said arm forms the supportfor the tubular member 90 (Fig. 2) which has a telescopic connectionwith the lower end of the fixed funnel 27. The lower end of the member90 stands close to the upper end 81 of the bag-holder when saidbag-holder is brought into the position shown in Fig. 2,

at which time the parts are in position to receive a charge of materialfrom the scalepan 26,- the material passing from the pan through thefunnel, through the tubular member 90 and into the bag held by thespring arms 82 and 83. In order to prevent the bag from becomingdisengaged from said arms 82 and 83, a spring 91 (Figs. 2 and 6) issecured to the arm 87 and extends downwardly and comes into contact withthe which is then positioned beneath the funnel.

The cams are so timed that after the requisite quantity or charge ofmaterial has passed from the funnel through the tubular section 81 andinto the bag, the shaft 43 is moved downward and as a consequence thetubular member 90 is moved downward together with the tubular section81. As the shaft moves downwardly the striker plate 65 is likewise movedand when the bag reaches a point adjacent to the fingers which standbeneath the lower end of the bag, the plate will strike the rollers 66and moved upward the shaft is given a quarter revolution. -This bringsthe charged bag which is still retained Iupon the bag-holder,

make a close fit with the tubular bag-holding section 81, the packerbeing carried upon thelower end of an arm 93 which is secured'at itsupper end to a bracket 94 attached to the upper end of a verticallyreciprocating shaft 95. Said shaft has secured to its lower end, beneaththe table, a link 96, which in turn is pivotally connected to the outerend of a lever 97, a roller 98 upon which coacts with the cam 10. Theinner end of the lever 97 is fulcrumed upon the fixed shaft 39heretofore referred to.

The cam 10 is so timed that it serves tolower the packer 92 into thebag-holder and its contained charge as the bag is lowered into one ofthe bag-forms or pockets'99 carried by arms 100 (Figs. 1 and 3) whicharms extend outwardly from a hub 101 secured to the upper end of theshaft 50. When the bag and holder are fully lowered into one of theockets 99 they come to rest upon a sector-s aped' plate 102 (Figs. 1 and3) which is secured to the upper face of the table and underlies thosepockets which are in operative osition with relation to the packer, andt e folding or tucking mechanism hereinafter referred to. The plunger orpacker 92 then descends and compresses the material in the bag-holderand by reason of the dwell formed in the cam 10 comes to rest. At thismoment the shaft 43 begins its upward movement and as a consequence itdraws the bag-holder from within the ba the packer holding the materialagainst andwise movement. The material is thus held until the bag-holderhas entirely cleared the bag, at which moment the packer begins itsupward movement and such movement continues until the parts come to theposition shown in Fig. 11, at which time the bag with its compressedcharge will be left in the bag- 'form or pocket 99.- When the shaft 43has reached its elevated position and the plunger 92 has cleared thebag-holder, and the bag-holder is clear of the bag, which has just beenwithdrawn therethrough, the shaft 1s given a quarter revolution which,of course, will bring another holder with a bag thereon into positionbeneath the funnel and likewise carry the bag which has just been filledto a position beneath the plunger, or to the positlon shown in Fig. 1.Wh1le this is being eflected one-sixth of a revolution will be impartedto the wheel-like structure or turret upon which the bag-forms orpockets 99 are mounted, and in so moving the charged bag will be broughtbeneath the mechanism by which a coupon or the like is discharged intothe bag and also beneath the devices which form the initial folds at theends of the bag. "This mechanism is best shown in Figs. 1 and 11 to 17inclusive. Extending upward fromthe base or table 1 is a verticaly-disposed post or column 103 shown in section in Fig. 16, and providedwith a vertical way in its forward face, into which extends a dovetailmember 104 of a hollow rectangular slide 105. Said slide is adapted toreceive a similarly shaped holder .or container 106, shown inperspective in to the post or column 103, the container bemounted uponthe opposite end of the sha ing thereby arrested in its downwardmovement while the slide moves on independently thereof. In the lowerend of the slide, and,

extending across the same in a horizontal direction, are two shafts 111and 112, each being provided with a series of rubber rings 113 which, aswill be seen upon reference to Fig. 16, are preferably staggered withrelation to each other. The shaft 111 carries a gear 114 which mesheswith a similar gear 115, mounted upon the shaft 112. Loosel 112 is agear 116 meshin with an idler 117, which in turn meshes w1th a rack 118fixed to the column or post 103. Splined to the outwardly-extending hubof the gear 116 is a disk 119 to which is pivotally secured a pawl 120,normally held by a spring 121 in operative relation with a ratchet-wheel122 pinned or otherwise secured to the shaft 112.

To the slide is secured a rod 123 which extends down to a point beneaththe table (see Figs. 1 and 5) and is pivotally connected by v a link 124to the outer end of a lever 125,

fnlcrumed at its inner end upon the shaft 39. Said lever carries aroller or bowl 126 (Fig. 4) which coacts with the cam 11. Theseconnections serve to raise and lower the slide 105 and to therebyactuate the shafts 111 and 112, which in effect are feed rollers, as theslide moves downward. By reason of the ratchet and pawl connection therollers are idle when said slide is' moved upwardly. When the parts arein their elevated position, or that shown. in Figs. 12 and 13, the feedrolls will be in contact with the lowermost coupon in the container.Immediately the slide starts to move downward the rollers will be turnedtoward each other and by reason of the rubber rings 11 3 bearing againstthe lowermost coupon said' coupon will be drawn in between the rollersand brought to the position shown in Fig. 15, at

which time the container has come to restupon the fingers 110, while theslide still continues its downward movement. The

motion of the rollers will be comparatively rapid and each coulpon thuswithdrawn from the container wi drop into the openmouthed package, whichat that moment stands immediately below the same.

By arresting the movement of the container and by having the rollersmove quite rapidly, there is no danger of more than one coupon beingwithdrawn at a time, and furthermore by stopping the rotation'of therollers while they are moved upwardly and again come into contact withthe lowermost coupon in the container, there is no danger of the couponsbeing torn, disrupted or thrown out of position in the container.

The slide 105 also carries the members which form twoinitial folds inthe upstanding edge of the package. 1 Each of said folders (of whichthere are two) is formed ofa plate 127 pivotally connected to the lowerend of a lever 128, fulcrumed at 129 upon a bracket or projection 130extending outwardly from the side of the slide. The

lever 128 at its upper end carries a roller 131, which, when -the slideis moved downward, comes into contact with a fixed cam 132 secured tothe post or column 103, thereby throwing'the' inner end of the leverinwardly against the action of a spring 133 which normally tends tothrow the lower end of the lever outward or into the position shown inFig. 12. The plate 127 is provided at each side adjacent to its innerend with an,upstanding wing 134.

The folders are so weighted that they normally stand in the positionshown in Fig.

12, in which position they leave a clear space for the passage of thecoupon into the open mouth of the bag, the folders retaining thisposition until the rollers 131 come into contact with the fixed cams132, at which time the inner ends of the levers are thrown inwardly andthe plates come against the upstanding edge of the bag and-serve to foldthe remote portions of the sides inwardly. As the slide is furtherlowered, the plates contact with the upper face of the bagform or pocket99 and, by reason of the position of the walls of said member 99 withrelation to the pivots of the plates, the latter will assume ahorizontal position, as shown in Fig. 17, the wings 134 coacting withthe plates to form the initial folds in the pocket. As the slide ismoved upwardly, the folders will swing outwardly and tilt upwardly,thereby readily freeing themselves from the bag. This freedom ofmove'rnent is also brought about by the fact that the wings 134 arespread outwardly toward their upper or free ends. as best shown.

to throw the two remaining upstanding sides of the bag outwardly to aslight extent. These operations will take place while the turret orwheel-like structure which carries the bag-forms or pockets 99 is atrest.

After the slide and its'allied parts have been moved upwardly, theturret is given a partial revolution, and such revolution carries thepartially-closed bag into operative relation with the mechanism whichfolds down the two remaining upstanding sides or edges. This mechanismis best illustrated in Figs. 1, 3, 18 to 21 both inclusive and 28.Secured to andextending upwardly from the table is a column or post 135,which forms the support for the final folding mechanism, thepaste-receptacle and the paste-applying mechanism by which paste orother adhesive is placed upon the third inturned fold or flap. Securedto a horizontally-projecting portion 136 of the column 135 is an arm 137which carries at its outer end the forward end. of a flap-retainingplate 138, said plate lying in the path of rotation of the pockets 99and extending from one pocket to another, as will be readily seen uponreference to Fig. 21. This plate is thin but is sufliciently rigid tohold the first pair of inturned flaps in their inturned position, andcomes into contact with said flaps formed by the folders just describedas the turret moves from beneath said folders into position where theremaining flaps are to be turned down and secured.

Attached to a block 139, which in turn is fastened to the member 136, isa plate 140, the forward edge of which stands in a substantiallyvertical plane, the plate being then gradually turned or twist'edthroughout its length until it assumes a horizontal position. Said plateengages the upstanding flap, designated by 141, and turnsthe same downover the retaining plate 138. At its rear or horizontal portion theplate 140 is cut away to permit a feed-roller 142 to come into contactwith the upper face of the inturned flap 141 to apply paste or otheradhesive thereto. Said roller is mounted in the lower end of areceptacle 143 into which extends a pipe or conduit 144, which is con--nected at its upper end to a suitable can or reservoir containing themain aste supply. The receptacle 143 is provi ed with a hollow,laterally-extending boss which fits over a pin 145 projecting outwardlyfrom one side of a U-shaped frame 146, which is pivoted at 147 to thepost or column 135. A spring 148 serves to hold the framein its elevatedposition and a stop screw 149 mounted in the member 136, prevents toogreat an upward movement of the frame under the action of the spring. Tothe lower free end of said U-shaped frame 146 is secured a block 150which carries a roller 151 adapted to coact with a cam 152 secured uponthe outer face of the bag-holder or form 99. Said block 150 is connectedto the frame 146 by a rod or stem 153 which passes through thelaterally-projecting free end of the U-shaped frame 146, a spring 154encircling the stem 153 and acting at its upper end against a collar 155secured to the stem. By reason of the fact that the lower end of thespring'rests upon the upper face of a laterally-projecting arm oftheframe 146 and its upper end against the collar, the block 150 willnormally be held close against the lower face of the U-shaped frame andwill not yield unless some extraneous material come between the roller142 and the inturned flap 141 of the package, or unless the flap itselfbe de-formed. The cam 152 normally draws the paste-roller down intocontact with the flap when the package is moving beneath the same, butthe construction just referred to permits the members to yield if thisbecome necessary. After the paste has been applied to the outer face ofthe third or inturned flap 141, which flap is still retained in itsclosed positionby the rearwardly-extending wing of the folder plate 140,the remaining upstanding flap 156 comes into contact with the upstandingor vertical edge of the final folding plate 157, which is supported uponthe outer end of the member 136. Said plate 157 gradually passes from avertical to a horizontal position and serves to force the flap 156against the pasted, 'inturned upper face of the flap 141, therebysealing the package. It is to be noted that the retaining plate 138during this operation underlies the flaps 141 and 156 and-consequentlythe fla 141 is rigidly supported while the paste is heing appliedthereto, and furthermore, the inturned flaps 141 and 156 are heldbetween the two plates while the paste or other adhesive is drying.After the flaps are thus secured, by moving the turret orbag-formcarrying member to the position shown in Fig. 24, the sealedpackage isbrought beneath the tubular member or package-guide 158 (seeFigs. 23 to 27 inclusive). Said member, as will be seen upon referencemore particularly to Figs. 24 and 26, is slightly flared at its lowerend, in order to facilitate the
